8 Powerful Foods For Lowering Your Blood Pressure
If your blood pressure (BP) is 140/90 mmHG or thereabouts, you either have hypertension or are tending toward it. You can check your BP from rising and even lower it with a careful diet. Begin with a heart-friendly diet called the DASH eating plan. Supplement it with beetroot juice, dark chocolate, pomegranates, oats, watermelon, garlic, flaxseeds, blueberries. And keep your sugar and salt intake in check.
In the United States, every 1 in 3 adults suffers from high blood pressure or hypertension.1This condition is characterized by a blood pressure level of 140/90 mmHg or higher. It can increase your risk for undesirable conditions such as heart disease, stroke, kidney disease, and blindness – to name just a few.2
If your blood pressure reading is 140/90 mmHG or above, you are suffering from hypertension.
Regulating your weight by staying active and eating right can go a long way in managing your hypertension. Here’s how diet can help you naturally control your blood pressure.
DASH To Lower Your Blood Pressure
The National Institutes of Health has developed an eating plan called DASH (Dietary Approaches to Stop Hypertension) designed to lower blood pressure.3 What it essentially asks you to do is fill up on foods rich in potassium, magnesium, and calcium and low in sodium. While sodium increases blood pressure, potassium neutralizes its effect. Magnesium and calcium both help in lowering blood pressure.
Load up on foods rich in potassium, magnesium, calcium, and natural antioxidants. Cut down on sugar and sodium.
Foods That Naturally Lower Blood Pressure
In addition to following the DASH plan, you can also reach for foods that help lower blood pressure naturally, like these:
A daily glass of beetroot juice may be all you need to keep your blood pressure in check.
If beetroots do not have a place in your diet, it is time to give them a second look. These top the list of foods that lower blood pressure quickly. A study found that blood pressure took a major plunge in healthy participants in about 3 hours after consuming 500 ml beetroot juice. The main player? Nitrate from the beetroot. Your body converts this natural chemical into nitric oxide, which dilates blood vessels and helps lower blood pressure.4
2. Dark Chocolate
Your body is constantly under attack from reactive free radicals that damage your cells. They also help in the accumulation of plaque in the arteries, leading to atherosclerosis, which ultimately hinders blood flow and causes hypertension.
Dark chocolate helps produce more nitric oxide, which dilates your blood vessels and reduces blood pressure.
Polyphenols (organic chemicals) found in cocoa, especially flavanols, boast powerful antioxidant and anti-inflammatory properties. They have been shown to increase the production of nitric oxide, which dilates blood vessels. In fact, a study in the Journal of Nutrition found that consuming 100 gm flavanol-rich dark chocolate daily for just 15 days reduced hypertension.
Furthermore, it improved glucose sensitivity in people who had high blood pressure and glucose intolerance. So go ahead and indulge in some dark chocolate. It is a real treat for your heart!5
Just 2 oz pomegranate juice daily can bring down your blood pressure by 21% in a year.
This delicious fruit has wonderful medicinal properties. A study in Phytotherapy Research delved into the effects of pomegranate juice by giving people with high blood pressure a daily glass (150 ml) of pomegranate juice between lunch and dinner for 2 weeks. Pomegranate, which is rich in antioxidants and bioactive polyphenols, was found to be effective at lowering blood pressure.6
In another study, atherosclerotic patients who had high blood pressure could bring down their systolic blood pressure by 21% after a year and reduced the thickness of the carotid artery by up to 30% by drinking just 2 oz pomegranate juice daily.7
If your blood pressure is inching toward hypertension, have a bowl of oats every day to keep it in check.
If you have hypertension, a simple bowl of oats can turn things around. Research has found that soluble fiber-rich whole oats have the ability to significantly lower blood pressure. They can also reduce the level of “bad cholesterol” in your body. Talk about a power-packed breakfast that can help your heart in multiple ways.8
This juicy summer fruit is loaded with amino acids (L-citrulline) which can increase nitric oxide production. Nitric oxide widens your blood vessels and is associated with lower blood pressure.
As little as 2 g watermelon twice a day for 6 weeks can help bring down systolic blood pressure, that is the first figure in your BP reading.
A study found that when people with hypertension ate 2 g watermelon twice a day for 6 weeks, they saw a reduction in their aortic systolic blood pressure (that is, the blood pressure when your heart beats as against the pressure between beats). The experiment also observed a decrease in the stiffness in arteries, ensuring that blood can pass through with ease.9
Garlic reduces your blood pressure by inhibiting the hormone that narrows your blood vessels.
When you crush or chop garlic, an organic compound called allicin develops. This substance dilates blood vessels and inhibits angiotensin II, a hormone that causes vessels to constrict. Various studies have found that garlic can effectively reduce blood pressure in people with hypertension.10So, aside from enhancing your food, this pungent bulb can take your blood pressure down a notch.
Flaxseeds are good for lowering blood pressure, probably because of their alpha-linoleic acid (ALA), which is a kind of heart-healthy omega-3 fatty acid, soluble fibers, and lignans, which are plant estrogens with antioxidant properties.
Flaxseed powder and oil can both reduce your blood pressure, with its omega-3 fat, fibers, magnesium, calcium, and helpful plant chemicals.
Moreover, just 1 tablespoonful (10.3 g) of whole seeds can meet 10% of your daily magnesium requirement and 2% each of calcium and potassium requirement.11 There’s negligible amount of sodium in these seeds, making them an ideal food for lowering blood pressure.
What form should you consume them in? Have flaxseed powder to lower your systolic blood pressure, and flaxseed oil and lignan extract to lower diastolic blood pressure. And to see best results, continue for at least 12 weeks.12
Here’s one more excuse to add these tasty berries to your fruit salads, shakes, and smoothies. The anthocyanins in them, which give them the brilliant blue color, are antioxidants responsible for good heart health.13
The anthocyanins in blueberries, which give them the color, are potent antioxidants that can reduce blood pressure and stiffness in the arteries.
Blueberries also help release more nitric oxide and thus help bring down blood pressure significantly, as in seen in a study on post-menopausal women with hypertension or pre-hypertension.14 The women were given 22g freeze-dried blueberry powder (equivalent to 1 cup fresh blueberries) daily for 8 weeks. It was found that their systolic blood pressure came down by an average of 5.1% and diastolic blood pressure came down by 6.3% and their arteries were less stiff than at the beginning of the study.
Follow The DASH Diet
What To Eat
Aside from nourishing your body with fiber and protein, these foods also provide vital minerals such as calcium, magnesium, and potassium.
- Opt for 4–5 servings of fruits and vegetables daily. Keep things interesting by focusing on a variety of colors and preparation techniques.
- Eat poultry, fish, and whole grains.
- Also eat nuts and low-fat dairy.
What Not To Eat
- Cut back on foods that are high in total fat, saturated fat, and cholesterol.
- Limit sugar intake.
- Minimize salt consumption. Aim for 1,500 mg sodium per day as recommended for hypertensive patients. This equals to less than 1 teaspoon (<6 gm) of table salt. Remember, table salt is not the only source of sodium. Everyday foods like soy sauce, baking soda, canned soup, and salad dressing are high sources of sodium. Keep tabs on your intake by carefully reading food labels.
Toning down your sodium consumption does not mean that you have to sacrifice flavor. Add onions, garlic, spices, and herbs to help your taste buds warm up to a low-sodium, heart-friendly diet.
